Iron Sulfide Oilfield Glossary

Drilling Fluids A group of compounds containing iron in 2 ferrous and 3 ferric valence states and sulfur in -2 sulfide valence states. Examples are ferric sulfide Fe 2 S 3 , ferrous sulfide FeS and iron disulfide FeS 2 , which is found in the minerals marcasite and pyrite.

Use Of Reactive Iron Oxide To Remove H2s From Drilling

Muds containing zinc sulfide could release H2S at any time if the mud should become acidic Table 1.While searching for a more effective material, we noted that ferrous hydroxide reacts with H2S under the fight conditions to form iron pyrite, which is insoluble even in concentrated hydrochloric acid. The proposed reaction is

Producing Iron Oxide Weighting Materials For Drilling

Such drilling fluids have a much lower apparent viscosity than drilling fluids which contain commercially available barite and known calcined pyrite. The gel strength and the water loss, two additional important parameters of a drilling fluid, are also much lower than those of drilling fluids which contain barite or conventional calcined pyrite.

Iron Pyrite Uses Amp Applications African Pegmatite

Aug 26, 2019 African Pegmatite is a leading supplier of iron pyrite, with the ability to provide the material in a range of grind sizes suited to any operational need. Pyrite is often mistaken for a precious metal, and for long periods of time was sold as one. Despite being an ore of iron and sulfur, it isnt the primary source of either material.

Pyrite In The Manufacture Of Iron African Pegmatite

Iron pyrite iron ii disulfide, FeS 2, herein referred to as pyrite is a naturally occurring sulfide of iron, and is one of the most common sulfides. Pyrite is found in large amounts in quartz seams, in sedimentary and metamorphic rocks, and alongside coal deposits. Aside from its metallic lustre giving it a visually attractive appearance, it finds use in industry in the manufacture of brake pads and as an additive in

Removal Of Pyrite And Different Types Of Iron Sulfide

Dec 06, 2015 Iron Sulfide scale is a significant problem in oil and gas industry where the iron sulfide depositions have adverse impact to the production operations. Typically, iron sulfide scale formed as result of the reaction between the hydrogen sulfide and iron. Iron sulfide scale has several forms pyrrhotite Fe 7 S 8 , troilite FeS, pyrite FeS 2 , greigite Fe 2 S 4 , and mackninawite Fe 9 S 8 .

Pyrite The Real Story Behind Fools Gold

Apr 01, 2014 In calcite and quartz veins, pyrite oxidizes to iron oxides or hydroxides such as limonite, an indicator that there is pyrite in the underlying rock. Such oxidized zones are called gossan, which appears as rusty zones at the surface. Gossans can be a good drilling targets for gold and other precious or base metals.

Use Of Reactive Iron Oxide To Remove H2s From Drilling

This paper describes the use of a specially prepared magnetic iron oxide to remove the H2S chemically from drilling fluids. This mud treatment protected the drillpipe from corrosion and prevented the release of toxic gases, allowing the well to be killed successfully.

Ocean Drilling Program Leg 207 Scientific Results Sulfur

Pyrite sulfur in black shales makes up between 30 and 100 of total sulfur. In addition to fixation of sulfide with iron, organic matter OM acted as an important sulfur trap during early diagenesis, with organic sulfur composing between 5 and 10 atom of TOC. The relative importance of OM sulfurization is increasing with its content.
